Application filed August 5, 1918. Serial No. 248,404.

automatically dumped, thereby resulting in y a great saving of time andlabor.

To this end the invention comprehends the provision of a scraper havinga platform upon which the operator is adapted to stand to hold the samein position for loading and prevent dumping after the scraper has beenloaded, enabling the material to be moved to any desired point.

The invention also comprehends the novel form of dumping means whichwill automatically operate to dump the scraper when the latter isrelieved of the weight of the operator, and said means including a pairof arms having one of their ends secured to the scraper near one endthereof and extending upward to the opposite end of the scraper andcarrying a weight which will overbalance the load and raise the end ofthe scraper to empty the same.

The invention further consists of the following novel construction,combination and arrangement of parts to be hereinafter more specificallydescribed and illustrated in the accompanying drawings, in which Figure1 is a plan view of a scraper constructed in accordance with the presentinvention;

Fig. 2 is a side elevation of the same with the scraper in loadedposition; and

Fig. 3 is a similar view showing the scraper in the act of dumping.

Referring to the drawings in detail, wherein like characters ofreference denote corresponding parts, the improved scraper comprises ascoop like member 10 Which is open at one end and has its opposite endand side edges provided with substantially right angular walls 11 and 12respectively.

Any suitable means may be provided at the open end of the scraper forconnecting thereto suitable motive power, while the opposite end of thescraper has extending transversely across the same a platform 13. Bracesor stays 14 extend diagonally across the scraper from the opposite sidewalls 12 and serve to stiffen and strengthen the same. The platform 13is for the purpose of providlng means upon which the operator may standwhen the scraper is being loaded or after loading, so that it will beheld in position to prevent dumping of the contents.

The invention is designed to provide novel means for automaticallydumping the scraper when the weight of the operator is removed from theplatform. This means consists of a pair of arms 15, each having one oftheir ends secured upon the outside face of the side walls 12 as shownat 16, said arms being curved and extending upwardly and outwardly withtheirfree ends spaced above the opposite end of the scraper. These freeends may be connected by a bar or cable 17, which may removably supporta weight 18, the latter being herein shown as a bag filled with sand orother heavy material. The weight of this bag is sufficient tooverbalance the weight of the opposite end of the scraper, so that whenthe said end is relieved of the weight of the operator it will be tiltedupwardly to dump the contents. For example the arms 15 may be securedeither upon the inside or outside faces of the side walls of thescraper.

The invention is susceptible of various changes in its form, proportionsand minor details of construction. For example, the particular form ofweight and the manner of securing it to the arms may be changed and theright is reserved to make these or any other changes that properly fallwithin the scope of the appended claims.

Having described the invention, what is claimed is:

1. A scraper embodying a scoop member, arms having one of their endssecured near one end of the scraper and their opposite ends extendingupwardly and spaced above the opposite end of the said scraper and aweight supported at the ends of the arms.

2. A scraper embodying a scoop member, arms having one of their endssecured near one end ofthe scraper and their opposite ends extendingupwardly and spaced above the opposite end of the said scraper, a weightsupported at the ends of said arms and a platform mounted upon thescraper at the end of which the arms are secured.

In testimony whereof I ailix my signature.
